Allen Bradley 1756-IR6I ControlLogix RTD Input Module

✔The Allen-Bradley 1756-IR6I is a ControlLogix 5555 processor module from the Logix5555 family, designed for high-performance, multi-discipline control in the ControlLogix 1756 platform. With 3.5 MB of user memory, this controller handles large, complex applications that combine discrete, process, drive, and motion control in a single chassis. It executes programs in a single, multitasking environment and communicates across Ethernet/IP, ControlNet, and DeviceNet networks, making it a proven workhorse for OEM machinery, packaging lines, material handling, and plant-wide automation systems.
